ABB Graduate Engineering Program (GEP)

would just like to check with you guys. has anyone of you gone through with this gep, and possible to share the application process?

reason being is that ABB actually called me on monday night and asked me to attend their AC tomorrow. so im not sure what to expect, because its the first stage im going for ABB. is it like a full day assessment with technical and psychometric tests and interviews, case studies etc? or is it like just a group presentation..?

read one review on glassdoor saying like the first stage was about 100 candidates shortlisted, then split into groups to do a case study. and the HR also told me should be done by noon, not sure about that because when she call me it sounds like she's trying very hard to fill up spaces (something like how a financial advisor would sell)
